How are bats affected by wind turbines?
Dead bats are found beneath wind turbines all over the world. It’s estimated that tens to hundreds of thousands die at wind turbines each year in North America alone.
Unfortunately, it’s not yet clear why this is happening. It’s possible that wind turbines interfere with seasonal migration and mating patterns in some species of bats. More than three quarters of the bat fatalities at wind turbines are from species known as “tree bats,” which tend to migrate long distances and roost in trees. These bats migrate and mate primarily during late summer and early autumn, which is also when the vast majority of bat fatalities at wind turbines occur. It’s also possible that bats mistake slow or stopped turbine blades for trees.

Pallid bat with transmitter
A Pallid bat (Antrozous pallidus) is outfitted with a radio transmitter to help lead us to its roost. The transmitter is attached with a temporary adhesive that will wear off within around 2 weeks, about as long as the battery life of the transmitter lasts. By following the bat USGS researchers will be able to learn what habitat types are important for this species,
...Western red bat release
Like most wild animals, bats often don't appreciate being handled for research purposes. However when holding bats after handling and examination, they often appreciate the warmth and need a little push to go. This Western red bat (Lasiurus blossevillii) was captured during USGS WERC research to learn more about the ecology, distribution, and movement patterns of
